I was in my first relationship from ages 17–23 and then quickly jumped to another one and now one of those it’s complicated things…so my “single at the bar getting bought drinks” experience is minimal. What I didn’t like is that it always seemed that the guy would chat me up, and the conversation would flow and all is well. But as soon as he offers to buy me a drink and I accept, he takes that as his cue to get waaaay too touchy feely / raised eyebrows-y at me and I get overwhelmed and shut it down.
Now at the ripe old age of 30 i’m the “I’m too old for this stuff” person at the drive bar with my close friends. Works for me!
